Somewhat higher confidence in the QPF totals brought about an expansion of the 2-4″ area. The GFS/NAM continue to suggest a snow hole in the northern VA and DC region, which remains a slight risk to the low side. Overall, I think risks are more to the high side, with localized 2-4″ totals possible within the 1-2″ contour. Likewise, the 2-4″ contour could see localized totals of 4-8″ (which is more so for the Appalachians than anywhere else).
